Oil cylinder with a clamping device: used on rolling mill for guide rail position adjustment; in case of power failure (whether intentionally or unintentionally), or hydraulic system failure and hydraulic cylinder function failure, the oil cylinder can fix the piston rod at its locking position without extra energy supply, so as to protect human safety and the machine.

Common specifications: piston rod diameter between 100 mm and 200 mm, clamping force between 20 KN and 75 KN;
Model: 125/90-1980
